Evaluating a global navigation satellite system (GNSS) receiver requires an accurate signal generator capable of simulating repeatable signals from many different satellites. The signal generator must create waveforms with different time delays, Doppler shifts, and power levels for accurately testing a GNSS receiver.
Being able to adjust these particular parameters of the generated signal makes it possible to evaluate a receiver's sensitivity to the desired signal and how susceptible it is to signals around it. At other times there may be a need to test a receiver within multiple constellations. In these instances, simulator software is an essential tool to evaluate GNSS receiver performance prior to development.
